Before the crossing, although Li Zhi did not take over the industrial design list of the textile industry, as an industrial designer, he also knew the structure of textile machinery and was very clear about the structure of the shuttle. The pen "Fun" Pavilion www.biquge.info where to install springs and how to arrange guide rails, Li Zhi knows.

On this day, Li Zhi spread out a piece of rice paper on the table, used a fine brush to stand some ink in the inkstone, and began to draw the design drawings of the various parts of the shuttle. Two quarters of an hour later, Li Zhi had already finished drawing five drawings.

Seeing Li Zhi drawing with a pen, Zheng came over puzzled and asked, "Zhi'er, what are you drawing?" ”

"Mother, I painted a new type of loom, which is several times faster than the loom you use."

Zheng Shi said in surprise: "There is such a loom? Impossible! So haven't I woven all the cloth in vain in the past few decades? However, the success of soap made Zheng trust Li Zhi's new idea, and couldn't help asking: "Zhi'er, where did you learn this loom?" ”

"An old Taoist priest taught me!"

"That Taoist priest again? How does he teach you so many good things? ”

Li Zhi smiled, did not answer his mother's question, and took the drawings to the blacksmith shop to find someone to make a shuttle.

When he went to the blacksmith shop, Li Zhi kept an eye on the different parts and handed over the different parts to several different blacksmiths to do, so as to prevent a single blacksmith from knowing the structure of the entire shuttle and copying Li Zhi's secrets.

In the Wang family's blacksmith shop, Wang Tietou, who was in charge, got the drawings of the spring, and looked left and right to see that he couldn't understand.

"What is Li Gongzi doing bending the fine iron like this?"

Li Zhi didn't answer Wang Tietou's words, but said: "You don't care what I do, you just do it." ”

Li Zhi was dressed in satin clothes, and his temperament was different from that of mortals. Wang Tietou was not angry when he was choked by Li Zhi, he just felt that people from rich and noble families should be so domineering.

"Li Gongzi, I will charge you thirty copper coins for making this thing."

"Well said!"

Even if Li Zhi is a plaything, what does he have to do with Wang Tietou? As long as Li Zhiken is willing to pay, it will be. Wang Tietou saw that Li Zhi was wealthy, so he stopped being verbose and began to make springs according to Li Zhi's drawings.

He burned a piece of fine iron red, put it on the anvil and beat it repeatedly, and beat it into a thick wire as thick as incense. Then he wrapped the thick wire around a stick with pliers, and made a spring, which he put in the water and quenched it.

When Li Zhi saw him make it, he was overjoyed, so he went to test the elasticity of the spring. But after trying a few times, Li Zhi felt that the elastic force of this spring was relatively average, and it would lose its elasticity and deformation if it was pressed too much.

Li Zhi thought about it and felt that this might be due to the lack of elasticity of iron. The springs of later generations are made of special spring steel, no matter how bad it is, it is necessary to use steel, and it is probably difficult to meet the requirements of springs made of iron, especially with the inferior iron of the blacksmiths of the Ming Dynasty.

"Wang Tietou, don't use iron to do this, find a piece of steel to do it!"

Wang Tietou was stunned and said, "Gongzi Li, good steel is used on the blade, and you also use stainless steel to make this thing, isn't it too extravagant?" ”

Li Zhi shook his head and said, "How much does it cost to make steel?" ”

Wang Tietou thought for a while and said, "I'm afraid it will cost a penny." ”

Li Zhi smiled and said, "If you do it boldly, I will give you a lot of silver." After a pause, Li Zhi said again: "You can knock this wire a little thinner, and it will be half as thick as this." ”

Wiping a handful of sweat, Wang Tietou said, "Okay! Since Li Gongzi is willing to give out the money, I will waste it. ”

Wang Tietou puffed up the bellows again and burned a piece of stainless steel that was found red. The bell rattled for a quarter of an hour, and the piece of steel was beaten into thin strips and wrapped around the stick. Finally, quenched, a steel spring is ready.

Li Zhi tried the steel spring and found that the effect was good. However, Li Zhi was not satisfied, and asked Wang Tietou to change the angle of winding, the thickness of the steel wire, and made more than a dozen different steel springs, and finally found the one with the greatest elasticity, so he gave up.

When you make a spring with a large elastic force, it will be easier for other components. Li Zhi asked several different blacksmiths to make guide rails and sink rails, and finally asked the carpenter to make a new loom with a width twice as wide as the Ming Dynasty loom and install the shuttle on it.

In order to keep it secret, the shuttle on the loom was wrapped by Li Zhi with several wooden boards, so that the loom operator could not see the structure of the shuttle.

After making the loom, Li Zhi took some cotton yarn from his mother and experimented with it. With each crossing of the warp and weft of the shuttle, the loom will return to the thread once with Li Zhi's operation, and the weaving speed is very impressive. Li Zhi operated for an hour and weaved a two-foot wide cloth, which was twice as efficient as the Ming Dynasty loom. In addition, the width of this loom was originally twice that of the Ming Dynasty loom, and the woven cloth was twice as wide, and the final overall efficiency was four times that of the Ming Dynasty loom.

Zheng stood aside, seeing Li Zhi's speed of weaving, with a look of disbelief. After 30 years of weaving, Zheng considers himself a veteran weaver and is proud of his ability to weave faster than the average person. But she never imagined that without experience but by the power of the machine, the weaving cloth could be so fast and so wide cotton cloth. If he hadn't seen it with his own eyes, Zheng wouldn't have believed that there was such a wonderful machine in the world.

Zheng looked at Li Zhi's loom and sighed. In the face of this new loom, won't my thirty years of hard work become stupid? If Li Zhi had come up with this kind of loom, wouldn't the output of his own weaving be several times more?

First soap, and then this loom, Li Zhi is no longer the stupid stupid son, but a son full of magic. I don't know why the Taoist priest Li Zhi said was so good to Li Zhi and taught Li Zhi so many wonderful things.

Zheng's surprise, Li Zhi didn't take it to heart. Anyone will be amazed at their own inventions, which are far ahead of their time.

made the shuttle loom, Li Zhi was in a good mood. It takes blacksmiths and carpenters to make this kind of loom, and the cost is about three taels of silver per piece, and Li Zhi can afford to make hundreds of them. Li Zhi planned to build a large-scale weaving factory, adding 400 looms and employing 400 weavers at one time.

This requires a very spacious building.

You can't find such a large factory in the city. The houses of the Ming Dynasty were all courtyard structures, the rooms were very small, the courtyards were large, and the land use rate was very low. If you put five looms in one house, you need eighty houses. In those days, there were eighty rooms, all of which were richly decorated! Li Zhi spent all his net worth and may not be able to afford it.

Li Zhi plans to set up a factory outside the city where the land is cheap, and find a vacant land to build a large factory.

If a loom occupies an area of three square meters, Li Zhi needs to build a factory building of 1,200 square meters. It's not a big project, and it's up to a few dozen carpenters and masons to do it quickly.
